Sweet spot is 88 to 94 percent of FTP. It sits above tempo and below threshold: hard enough to build muscular endurance and raise FTP, easy enough to repeat several times a week without wrecking the rest of the block.
Some coaches draw the band wider, roughly 84 to 97 percent, and the exact edges matter less than the idea behind them. The point is the intensity where training benefit per hour is highest relative to how much recovery it costs.
That balance is why sweet spot sessions are common in indoor plans. They deliver substantial time near a productive aerobic ceiling without the recovery cost of constant threshold or VO2 work.
What sweet spot training improves
Sweet spot work is useful when a rider needs more sustainable power, more tolerance for long steady efforts, and better ability to handle quality work during busy weeks.
It is often one of the most practical session types for time-constrained riders because it gives a lot of training signal in 45 to 90 minutes.
- •Muscular endurance for longer efforts
- •Tolerance for steady sub-threshold work
- •Progression toward stronger threshold performance
How to place sweet spot workouts in the week
Sweet spot should usually support the week, not dominate it. One or two sessions can work well in a balanced plan, especially when surrounded by easy endurance, recovery, or skill work.
If every medium-hard day becomes sweet spot, riders often drift into a gray-zone routine that is not easy enough to recover from and not specific enough to maximize higher-end development.
Signs your sweet spot work is set correctly
Good sweet spot intervals feel controlled but demanding. You should finish them worked, not destroyed. If your cadence falls apart and every interval turns into a near-max effort, the session is probably set too high or placed poorly in the week.
That is where plan context matters. A good plan keeps sweet spot sessions productive by balancing them against harder workouts and recovery days.
Building sweet spot workouts in VeloWorkout
The simplest pattern is a controlled warmup, one or more sustained active blocks, short recoveries, and a cooldown. Percent FTP targets make these sessions easier to reuse as your fitness changes.
The library is a good starting point if you want examples, and Builder is the right tool when you want to change interval length, cadence cues, or progression from week to week.
Common questions
What percentage of FTP is sweet spot?
88 to 94 percent of FTP is the range most plans use. Some coaches stretch it to 84-97 percent; the useful definition is the band just under threshold where you get most of the aerobic benefit for a fraction of the recovery cost.
Is sweet spot the same as tempo?
No. Tempo sits lower, around 76-90 percent of FTP, and feels conversational-but-working. Sweet spot starts where tempo stops being comfortable and ends before threshold, where the effort stops being repeatable.
How long should sweet spot intervals be?
Eight to twenty minutes is the usual range, with two to five minutes of easy spinning between them. Thirty to sixty minutes of total time in the band is a productive session for most riders.
How often can you do sweet spot work?
Two or three sessions a week is sustainable for most riders during a base or build block, provided the rest of the week is genuinely easy. It is repeatable in a way threshold and VO2 work are not, which is most of its appeal.
